You would need to do two things
1) alter the query to retrieve the poster's information and edit the loop to add that information.
2) add the new variable (the one added in the loop) to the template so that it displays.
Adding the forum works similarly.

I don't have the query offhand but if you look at your table through mysql (via phpmyadmin) you should be able to see what you need.

If you can't figure it out, give me a few days (or as soon as I get time) and I will add it. Usually I do most of my updates on the weekends.
